CARL I-I. CARLSON, OF IRON MOUNTAIN, MICHIGAN.

BUTCHERS-BLOCK SCRAPER.

Specification of Letters Patent.

Application filed March 18, 1911. Serial No. 615,291.

To all whom it may concern:

Be it known that I, CARL I-I. CAnLsoN, a citizen of the United States, residing at Iron Mountain, in the county of Dickinson and State of Michigan, have invented a new and useful ButchersBlock Scraper, of which the following is a specification.

This invention relates to wood working tools, and more especially to scrapers; and the object of the same is to produce an improved device of this kind for the use of the butcher when he desires to scrape his meat block. It is well known that these blocks, which are constantly being used for the purpose of cutting, sawing, or chopping meats thereon, soon become foul because their upper surface is saturated wit-h the juices from the meat; and it is necessary to cleanse them from time to time, especially in warm weather. To do this a peculiar form of scraper is needed, and the present invention is an improvement on the devices which are now on the market for this purose. p The following specification describes the details of my invention, reference being had to the accompanying drawings wherein- Figure 1 is a side elevation of this scraper complete, showing one form of handle. Fig. 2 is a plan View thereof, the handle being in section on the line 2-2 of Fig. 1. Fig. 3 is a cross section on the line 3-3 of Fig. 1. Fig. 4 shows two other forms of handles which I may employ, the scraper head being in section to illustrate their manner of attachment.

In the drawings the reference numeral 5 designates a band of steel standing on edge and forming what might be called the frame of the scraper head. Beginning at the point 6, this band extends straight down one side as at 7 then curves around one end of the body as at 8, and is then continued in an oblique blade 9 which terminates at the point 10. A companion frame member designated by the numeral 15 begins at the point 16 where the bend 8 merges into the blade 9, extends straight along that side of the body at 17, curves around the opposite end. as at 18, and finally extends into another oblique blade 19 which terminates at the point 20. This point 20 is within the curved end 8, whereas the extremity 10 of the first-described frame member is within the curved end 18, and these two frame members being duplicates of each other are therefore complementary so that when properly assembled they produce an oval frame as best seen in Fig. 2. lVithin this frame are assembled several blades 21 and 25, the former extending from the point 20 parallel with the straight sides 7 and 17 and terminating at points 22 within the curved end 18; and. each oblique blade 25 also extending from one curved end 8 to the other 18, but leading diagonally across between one straight blade 21 at one extremity and the next adjacent straight blade at the other extremity of the scraper head. Thus is built up of steel bands an inclosing oval framework of two complementary members and an inclosed scraper body of straight and. oblique blades all housed within said frame. Finally, as best seen in Figs. 1 and 4, the lower edges of all these bands of steel are provided with coarse teeth 26 throughout all of their length except at and near the ends of the head of this scraper, and at these points the teeth are finer as shown at 27 so that they do not project downward quite as far as the coarse teeth 26. One other essential feature of the head of this scraper is the means for holding all these bands in position, and I preferably use two ties for this purpose, one disposed near each rounded end of the head and extending across it at right angles to its longer axis at points where the oblique blades 25 have contacted with the straight blades 21 so that the blades all here stand longitudinal ofthe head asishown. Between them I dispose tubular collars 30 located in direct alinemcnt with each other, and the various bands themselves have holes 31 which are by preference of the same size as the bore of the collars, and throughout the bore and the holes I pass a rod 32 which is of a sizeto fit closely but removably therein. The extremities of this rod may be treated in any desired manner to effect the end in view. In Fig. 3 they are upset or headed as at 33 so that the rod becomes in effect a long rivet. At the left of Fig. 2 one end of the rod has a screw head 34 and its other extren'iity 35 is threaded into a nut 36. At the right end of this view one extremity of the rod has an angular head 37 and at the other end is a nut 36, so that the rod in this case becomes a bolt; and obviously both constructions shown in Fig. 2

permit the removal of the rod whereas itcould not be so easily removed if it were a rivet as shown in Fig. 3.

is the bracket which may or scatter the scrapec Butchers scrapers of this kind may be and sometimes are successfully treated by means of thorough washing, and sometimes even the cleansing treatment is carried to the extent of boiling the tools so as to sterilize them; but I prefer to take the bands apart at times, especially when it becomes desirable to sharpen the teeth referred to above, and of course if the ties employed are removable the bands can be readily taken apart and reassembled when desired.

The handles by which the tool head is manipulated may be made in a variety of shapes according to the wishes of the user. In Fig. 1 a straight bar 40 is shown, round .in contour and having near its ends depending brackets 4:2, each of which has an eye 41 at its lower end surrounding the tie as indicated; and probably this is the simplest form of handles which could be provided. In Fig. 4. I have shown two other types of handles which I may employ. In each the numeral 50 designates the handle or handhold proper which is preferably of wood or some material agreeable to the user, and 52 be of metal here also again having an eye 51 adapted to take the place of one of the sleeves or collars 30 upon the rod 32, as is the eye 41 of the other handle, shown in Fig. 3. But in this case, as there would be a handle at each end of the tool head, instead of locating the bracket about vertical as shown at L2 in Fig. 1, I dispose the metallic brackets 52 longitudinally between two of the adjacent blades so as both to strengthen the latter and to give rigidity to the handle, and at remote point-s through this bracket I insert a pin 55 longer than the thickness of the bracket and whose extremities will take into holes 56 formed in the adjacent blades as indicated at the left of Fig. 2. It is obvious that when the several bands forming the head are taken apart by first removing the ties, the handles of either character can be disconnected from the remainder of the device and cleansed at the same time. If both designs of handles are used as shown in Fig. 4, the device can be grasped in both hands as is an ordinary bench plane, and perhaps this construction of handles would be preferred where the scraper is made quite large.

The hand-hold in any construction may be of wood or some material which can be sterilized, but otherwise all parts of this device are preferably of metal, and the sizes and proportions of parts are not essential to the present invention.

I might add that in other devices of a similar character now in use I have found that where the blades or the teeth on the .blades are permitted to have a certain spring motion when i action, they throw up pieces of wood,

particles of meat, and juices; and I therefore desire it distinctly understood that the proportions of parts in the device above described should be such that the ties will hold the blades practically rigid so that spring action is avoided, especially if this device be reciprocated over the block in a direction which is nearly or precisely in line with the longest axis of its head. This rigidity is borne out by the curved ends 8 and 18 of the head which come in close contact with the extremities of all the blades and by the fact that half of the latter are straight and the other half are oblique so that they have the effect of bracing the straight blades, added to which are the sleeves or collars 3O interposed between the blades and spacing them rigidly apart, combined with the bolts or rivets or whatever form of tie is employed to hold the whole in one compact and rigid mass. Obviously the user grasps the handle or handles in his hand or hands and reciprocates the head of the device over the block or board to be cleansed, exerting suflicient pressure so that the teeth out into the upper surface thereof and wear it away. These teeth are intended to be of suitable size in order that the device will not scratch the block on lines which will be perceptible, but will merely wear away its surface which has become fouled. The purpose of making the teeth finer at the extremities as at 27 is because, no matter how carefully a user may endeavor not to, I have found by experience that at each end of each stroke he will exert a little tilting action upon the handle so that the head may be said to be rocked slightly at these times. By making the extreme teeth less pronounced or shorter, a little rocking is permitted without injuriously affecting the block being scraped or excessively wearing off the teeth at these points.

WVhat is claimed is:

1. In a scraper of the character described, an oval head including a frame made of steel bands having teeth along their lower edges, and a plurality of blades in said frame comprising alternately disposed members parallel with their straight sides and other members obliquely interposed between the straight members, said blades having teeth along their lower edges; means for holding said bands in position within the head; and a handle for the whole.

2. In a scraper of the kind described, an oval head including a frame made of two like and complementary steel bands, each starting from a certain point in said head, forming one straight side thereof, thence continued around one curved end thereof, and terminating in an oblique leg; and a plurality of blades within said frame comprising alternately disposed members parallel with its straight side and other members parallel with the oblique legs and interposed between the straight members; nseans for holding said bands in position within the head; and a handle for the whole.

3. In a scraper of the character described, the combination with a head made of steel bands standing on edge and including a surrounding frame, and a plurality of blades within said frame comprising alternately disposed members parallel with its straight sides and other members obliquely interposed between the straight members, said blades having teeth along their lower edges, the teeth at the extremities of said oval head being less pronounced and not so long as those elsewhere located, the frames and blades having registering holes; collars interposed between the bands with their bores registering with said holes, tie rods exs tending throughout said collars and the holes in the bands and having heads at their opposite extremities; brackets mounted on said rods, and handles carried by said brackets.

In testimony that I claim theforegoing as my own, I have hereto affixed my signature in the presence of two witnesses.
